Elements in soils & plants
Of the seventeen essential plant nutrients, fourteen are acquired directly from the soil. These fourteen essential nutrients make up a miniscule 4% to 5% of plant matter, but without all of them a plant could not complete its lifecycle. Plant nutrients are separated into ‘macro-‘ and ‘micro-nutrients’ based on their relative abundance in plant tissue. Micronutrients are those found in concentrations less than 100 ppm in plant tissues. Natural soils typically have sufficient total amounts of each micronutrient, but conditions and element properties limit availability for root absorption and plant utilization. In some places the parent material (rock) that the soil developed from is deficient in some elements and fertilization is essential to meet crop demands.
Numerous factors limit nutrient availability in soil, including: soil moisture and aeration levels, texture (the relative amounts of sand, silt and clay), organic matter content, pH, temperature, abundance of other nutrients, heavy metal content, bicarbonate content, and biological activity. This myriad of factors limits plant growth, not because the nutrient isn’t present, but in a form unavailable to plants. In soilless and hydroponic systems several of the same factors limit nutrient availability.
Under artificial growing conditions it is largely nutrient imbalance, high concentrations of other nutrients in solution and high solution and media pH that negatively affect availability of the micronutrients iron, copper, manganese and zinc. In soilless systems plants are grown in an inert media and all nutrients are supplied dissolved in water. Assuming initial nutrient concentrations are correct, imbalances can occur when nutrients accumulate in the growing media and solutions in recirculating systems are not changed frequently enough (every 1 to 2 weeks). Nutrient solution pH and media pH will change over time as the balance of nutrients changes and roots excrete pH altering compounds.
Increasing pH corresponds with decreasing availability of iron, copper, manganese and zinc. This is partially why hydroponic nutrient solutions should be between 5.5 and 6.5 and optimum pH for garden soils is 6.2 to 6.7. This is the pH range with the highest availability for the entire range of essential plant nutrients. For example, above pH 4 each unit of increase in pH decreases iron solubility by a factor of about 1000. If the pH is too low availability of these metals may become so high that toxicity becomes a concern.
As growers we manage our gardens to match nutrient availability with crop demand, but some things are beyond our control. Outdoor growers are limited by the soil and climate nature provides and indoor growers balance the pros and cons when selecting a production system. Despite our best efforts to create ideal conditions, the nature of some metal nutrients precipitates the need for chelation.
